6 Claims.

This invention relates to improvements in liquid container constructions such for example as oil cans and pertains particularly to an improved valve means for the pouring nozzle thereof.

The primary object of the present invention is to provide a novel valve for closing the pouring nozzle of a liquid container, which valve is adapted to be easily and quickly actuated to opened or closed position.

Another object of the invention is to provide a valve for the pouring nozzle of a liquid container which is so designed that it will continue to operate efficiently to maintain the pouring nozzle closed even though the latter become damaged or bent while in use.

A- still further object of the invention is to provide a'novel flap valve for closing the inner end of the pouring nozzle of a liquid container and novel means for securing the valve against its seat to maintain the nozzle closed.

A'still further object of the invention is to provide a valve device for the pouring nozzle of a liquid container having a novel actuating means and novel means associated. therewith whereby leakage of the contents of the receptacle through the aperture in the receptacle wall through which the said actuating means extends to the exterior of the receptacle is prevented for a period, if the receptacle is upset.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure I is a transverse sectional view through a receptacle constructed in accordance with the present invention and looking at the under side of the top thereof, the section being taken substantially upon the line 1-1 of Figure 2;

Figure 2 is a vertical sectional view taken upon the line 2-2 of Figure 1;

Figure 3 is a view in top plan of a portion of the top of the receptacle showing a detail of the invention.

Referring now more particularly to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates a receptacle of the type commonly employed for coal-oil or similar liqent invention, is extended inwardly through the top 2 and this inwardly extending portion which is indicated by the numeral 5 forms a seat for a flat valve disk 6.

The pouring nozzle has fixed in the outer end thereof the member 7 which is formed to provide an eye in which one end of a coil spring 8 is engaged, the other end of which spring is attached to the central part of the valve disk 6 as hereinafter described.

Secured to the inner side of the top 2 is a pair of guard members each of which is indicated by the numeral 9 and which are located upon opposite sides of the valve disk 6. These guards are shown as being in the form of elongated loops or staples which are mounted to extend in planes converging at the rear or inner side of the valve disk 6. Since the guard members 9 are disposed in relatively close proximity to the disk 6 it will be apparent that the disk cannot be shifted laterally on its seat but will be stopped by these guards, nor can it slide rearwardly on the seat but may oscillate rearwardly, fulcruming against the guards.

The disk 6 carries a double eye 10 to oneeye of which is loosely connected one end of a link 11. The two eyes are separated by the disk 6 and the other eye has one end of spring 8 connected therewith. Secured to the under side of the top 2 is a cylindrical box 12.

The inner end 13 of this box 12 has an aperture 14 therethrough and in alignment with this aperture there is formed, in the top 2 which forms the outer end wall of the box, a similar aperture 15. Extending through the box 12 and through the apertures 14 and 15 is a shaft 16, the inner end of which is angled to form the crank arm 17 which is looped at its end as indicated at 18 to facilitate the connection of the other end of the link 11 therewith. The outer end of the shaft 16 is also angled to form the arm 19 by means of which the oscillation of the shaft is effected, as will be hereinafter described.

Upon the outer face of the top 2 there are mounted the angularly related plates 20 and 21, in the angle of which the outer end of the shaft 16 is located as is shown in Figure 3. One of these plates, as for example, the plate 20 extends transversely of the top of the can, while the other extends obliquely therefrom and the obliquely directed plate limits the swinging movement of the arm 19 when it is shifted to permit the valve disk 6 to close the inner end of the pouring nozzle 4 while the transversely directed plate limits the swinging movement of the arm when it is shifted to open the valve.

In the operation of the present device the user of the receptacle oscillates the arm 19 to the left and thus swings the crank arm 17 to pull the valve disk 6 from its seat against the tension of the spring 8 and rearwardly from the nozzle between the guards 9. The rear edge of the valve disk pivots against the adjacent legs of the guard staples 9 and thus causes the disk to pivot and swing back away from the end of the nozzle.

While, of course, the movement of the pull rod or link 11 is limited, the guards would prevent the movement of the disk beyond a predetermined position even if this were not so. It will be readily apparent that in order to effect the closing of the nozzle it is merely necessary to start to swing the arm 19 in the reverse direction whereupon the spring 8 will take control to pull the disk back onto its seat.

By providing the box 12 the leakage of the contents of the receptacle, through the aperture provided for the extension of the shaft 16 to the ex terior thereof, is prevented for a short period if the receptacle becomes upset and the slight space which exists between the shaft 16 and the edges of the apertures through which it passes permits the necessary inflow of air to the receptacle to prevent a reduction of the air pressure therein and interference with the flow of fluid though the nozzle 4.

Having thus described the invention, what is claimed is:-

1. In a receptacle having a pouring nozzle, a valve seat formed at the inner end of the nozzle and constituting a continuation of the same through the attached receptacle wall, a valve disk normally resting against said seat, a contractile spring disposed within the nozzle and having one end secured thereto and having its other end secured to the disk, a pair of guard members mounted on the receptacle and projecting inwardly and disposed with the disk therebetween, a shaft oscillatably mounted in the top of the receptacle and having an outer end portion formed to provide an arm and an inner end portion formed to provide a crank, coupling means between the crank and the disk whereby upon oscillation of the shaft the disk will be drawn from its seat, said guard means guiding the movement of the disk and preventing it shifting laterally from the seat, and a hollow receptacle surrounding the shaft and disposed within the receptacle, for retarding the leakage of the receptacle contertits about the shaft when the receptacle is upse 2. A receptacle having a top, a pouring nozzle secured in and extending at one end through said top whereby the inner end edge thereof is disposed inwardly of the inner surface of the top to form a disk valve seat, a disk member constituting a valve positioned against said seat, a double hook element secured to the center of said disk with a hook upon each disk face, a contractile spring secured at one end to one hook and having its other endsecured within said nozzle adjacent the outer end thereof and normally pulling said disk onto the seat, a link element eeaovs secured at one end to the other hook, oscillatable means operable from the exterior of the receptacle and connected with the other end of said link element whereby the removal of the disk from its seat is effected, and guard elements carried by the top of the receptacle between which the disk moves and by which the disk is guided relative to the seat.
